I am new to this forum so please forgive me if I'm not following proper protocol. My radio went completely dead (totally blank screen) then if I let the car sit for 2 or 3 days the battery is completely dead. I have AAA and they keep saying it's a bad battery. They put the third new battery in two days ago and again it's dead. No charge for the batteries but I need to find the cause and Don't know where to start. I was hoping someone could point me in the right direction. It's an '04 coupe and totally stock. Any help will be greatly appreciated. Thanx
